Hi,
I am trying to install Cacti on windows server 2012. As I checked the Firefox browser, the javascript is enabled. I verified that using "about:config" and search for javascript entries.
However, when I enter "/cacti" in the browser, it says 

You must have JavaScript enabled for this to work.
Any thought on that?

Regards,
Mahmood
